From the outset you feel this is just more eco propaganda wrapped up in a TV Sci fi thriller. If that's what you are into, you won't be disappointed.
However, the writing/dialogue is sketchy at best, the CGI is woeful, there's a strange looking American woman also with more fillers and botox than you've ever seen pumped into a single person and well...... it's all just a bit naff.
It starts OK, but by the end of episode 2, it's clear where the narrative is going and they are just going to keep beating the eco-drum all the way through, with the storyline secondary to the drumbeat and the acting clearly doesn't even count so long as the message is broadcast.
